Realtek ALC272 Sound Card Trouble


I am having trouble with my onboard sound card. The onboard sound card is a Realtek ALC272.

I am running OpenSUSE 13.1 KDE, Kernel Version 3.18.6-1.gec2a744-desktop.

If I open kinfo Centre I can see my hardware correctly. (See Image Below)
If I then Open YaST >> Harware >> Sound, and take a look at the the Sound Card Model my system has chosen Card Model - SBx00 Azalia (Intel HDA) if I press “add” and try and find my Sound Card Model it does not appear here. If I press the tick box for “show list of Kernel Modules” I do not see the module here. If I then go over to terminal and type “lsmod” I see a number of “snd” modules I also see “snd_hda_codec_realtek” which to me says the system has the correct codec and is why kinfo is able to identify the card, so why is YaST having issues?

I am pretty new to Linux so would appreciate any help on this matter.

Thanks in advance, scroll down to see some screen shots

Please post your dmesg output regarding Realtek and sound and wrap it with code tags

Like this!

Most of the dmesg output will be meaningless so you can remove it.

dmesg > derp.txt

Would redirect it to derp.txt for easier editing.

Make sure you have kernel-firmware package installed and reboot.


I forgot to add the alsa-info

This may help



I have the kernel-firmware instsalled. THe DMESG is too long for me to add in here. Which part are you interested in?
Thanks for the tip on Code tags

Looking at the pictures, you already have the ALC272 configure properly - perhaps it’s a case of the audio output device being wrong.

  • First since you are using KDE, go to Configure Desktop -> Multimedia -> Audio and Video Settings and check the Audio Playback order. Make sure the audio output device you want to use is at the top.
  • Second, install a program called Pavucontrol and fire it up. Then choose your output device and try to play audio.


So the picture showing YaST where the device is being recognized as ABx00 this is correct?? I was expecting it to be recognised as ALC272 like in kinfo. Why is this not the case?

In the Setting the order is correct I am only seeing something called “Built in Analog Stereo”

I have now installed pavucontrol and launched it.

I am more interested in the audio input to my machine.
Back in december I was able to send a line in with audio from my ipod and detect it, this is no longer working. I have gone to configure and changed the profile to analog input and duuplex and played with the levels all I am getting is white noise.

Any Ideas
